2 pipe steam and condensate pumps

Steamhead (in transit)

or more accurately, what pressure is actually needed?

And what is your "B" dimension?

If these things can run below the level of pressure that would overcome the "B" dimension, you don't need the pumps. Gravity return should work fine.

2 pipe steam and condensate pumps

I lokked at a condo building today consisting of 4 buildings each building has 4 units each building has a 2 pipe steam systeam with traps and condensate pumps are the condensate pumps really needed?

pumps.

Hmmm.

How many boilers, how many pumps.

If one boiler, methinks (depending on the altitude of the water line vis a vis the returns) a condensate vented receiver and a boiler feed pump would give a more predictable water line. Unless these are vacuum condensate pumps, where it is advisable to leave them in place. Of course the best set up (but not the cheapest) is an arrangement with vacuum return pumps feeding a receiver and separate boiler feed pump.

If I don't respond this evening, its 'cuz I'm at Dan's Steam night School in Cleveland. Woohoo!

How are they set up, Ed?

I would assume that they should stay absent other information and as Terry suggested. Must have been a reason for them, probably a lift issue or as Terry suggested, vacuum. Rather doubt vacuum in a small building but could be at the outside of my experience.

They may be set up as straight receivers to hold excess volume from warm-up surges (empty on high level float control) or used as boiler feed units (empty on demand from boiler level control). I would tend to think boiler feed control if they do not feed into a bona-fide boiler feed unit downstream.

If they are cast iron you could leave them and rebuild/replace the pumps and/or controls on the remaining receiver.

yup, i'm thinkin along those lines too..

i see pumps put in alot on systems that don't need them..there usually is no legitimate reason for pumps on an old system since it probably didn't originally have them..me like'um gravity..
